Abstract

Mouse toxicity due to microcystin (hepatotoxin) was detected in water bloom of a local lake, comprising mainly Microcystis aeruginosa. Both toxicity and biomass content of the phytoplankton varied seasonally. Incubations with an algicidal metabolite from Oscillatoria late-virens and a herbicide 3-(3,4-dichlorophenyl)-1, 1-dimethyl urea (DCMU) caused depigmentation and detoxification in bloom samples. Algicide-incubation also encouraged growth of protozoa and bacteria, pathogenic form included.
